Lightbulb resembles a large class incandescent Light Bulb, an electric bulb which produces light with a wire filament heated to a high temperature by an electric current passing through it until it glows. Her face appears on her glass bulb, which is large and shiny yellow. Within her glass bulb, she has a stem sticking out above her metal sleeve. Lightbulb's arms and legs protrude out of her grey metal twisted sleeve, followed by an electric foot contact between her legs.
